PRESSURE-*SOCKET FOR CURTAlN-POLES.

SPECIFICATION forming part of Letters Patent No. 452,965, dated May 26, 1891. Application filed July 3, 1890. Serial No. 357,659. (No model.)

To aZZ whom may concern: said cap-piece A for the insertion of the end Be it known that I, JOHN G. BBOTHWELL, of the curtain-pole O. The bridgepiece B, of Torrington,in the county of Litchfield and however, which is secured within the cap- St-ate of Connecticut, have invented a certain piece A, is of arched form and recedes from 5 new and useful Improvement in Pressure the outer end of the cap A and is provided Sockets for Curtain-Poles, of which the fol centrally with a screw-threaded perforation lowing is a specification. b for the reception of an adjusting-screw, as My invention relates to an improvement in will hereinafter appear. A cap-piece D,quite pressure-sockets for curtain-poles for use in similar in its general construction to the cap- 1o connection with poles which are to be suppieces A and A, hereinbefore referred to, is

ported between two opposite jambs of a door adapted to receive with a loose fit the oppoor window or other recesses, the object being site end of the pole O and is provided across to provide a simple,inexpensive, and effective its outer end with a straight bridge-piece E, arrangement for securing the pole firmly in having its central portion preferably widened, 15 its position and at the same time provide for as shown at e. The bridge-piece E is proits ready removal. vided at its ends with laterally -projecting A practical embodiment of my invention is lugs e.

The bridge-piece B, secured to the the ends of the pole abut until the ends of cap -piece A, preferably extends straight the cap or socket pieces A A come into con- :00 50 across the outer end of the cappieee, leaving tact with said wood, when the pole will be a free space between it and the inner end of firmly secured in position. The rim G effectually conceals the adjusting mechanism, giving the pole at all times a neat appearance, and the pole may at any time be taken down by simply rotating; the socket-piece G D in the opposite direction. The construction is such that the bridge-pieces, with their supports, maybe cast of iron or other cheap metal, while the cap or socket pieces may be formed very thin and made of a more expensive or ornamental metal, and the screw-threaded perforation and screw are of such a size as to render them easy to manufacture and quite inexpensive.

It will be obvious that the improvement is applicable just as well to poles made of hollow brass tubing as to those made of wood.

What I claim as my invention is- 1. An adjustable socket-piece for the end of a curtain=pole, comprising a stationary cap or socket provided with a bridge-piece secured thereto and having spurs projecting outwardly from the end of the cap or socket, and a rotary socket-piece adapted to receive the end of the pole and provided with a screw having an engagement with the bridge-piece carried by the stationary cap or socket, sub

stantially as set forth.

2. The combination, with a curtain-pole, of stationary caps or sockets located at the extreme ends of the pole and provided with bridgepieces secured thereto and having spurs projecting therefrom, and a rotary socket-piece having a loose engagement with one end of the pole and a screw-threaded en-,

gagement with the bridge-piece in one of the stationary caps or sockets, substantially as set forth.

3. The herein-described adjustable socket, consisting of a stationary member provided with an arched bridge-piece and having outwardly-extending supports, and a rotary member provided with a socket for the reception of the end of the curtain-pole and with a socket for the reception of the stationary member, the said rotary member having a screwthreaded engagement with the bridge-piece of the stationary member, substantially as set forth.

4. In a curtain-pole socket, the combination, with an annular band having lips projecting from one of its edges, of a bridgepiece adapted to extend diametrically across the end of the annular band and provided with laterally-extending lugs at its ends, the said lips and lugs forming a fastening to secure the bridge-piece in position, the said bridge-piece being provided with a screwthreaded socket for the purpose of adjustment, substantially as set forth.
